The Trump administration has concluded a six-week nationwide sweep of suspected gang members with 1,378 arrests — the largest such gang sweep conducted by the U.S. Immigration and Customs Enforcement’s Homeland Security Investigations (HSI) to date.

The operation, which ran from March 26 through May 6, targeted gang members and associates involved in transnational criminal activity, including drug trafficking, weapons smuggling, human smuggling, sex trafficking, murder and racketeering.

“Gangs threaten the safety of our communities, not just in major metropolitan areas, but in our suburbs and rural areas, too,” ICE Acting Director Thomas Homan said Thursday. “Gang-related violence and criminal activity present an ongoing challenge for law enforcement everywhere.”

Illegal immigration poses a major security threat by letting these types into the country.

And Trump just proved it. He also demonstrated exactly how he is going to deal with the problem.
